Yours!

Members of a Private Email Network (PEN) are often curious about which time zone the tracking is recorded and displayed in. The short answer is, email2 times and dates are synced with the time and date of wherever you happen to be at the moment. If you're on a laptop in Seattle, and the tracking says "Retrieved at 2:45pm," then a desktop in New York is going to see "Retrieved at 5:45pm." The tracking dates and times are always in "your time."

This is achieved by recording all dates in Universal Time (GMT) and using your local settings to provide the proper offset. This ensures that you always know when things are happening in the proper frame of reference.
